"The large congregation witnessed the healing. All noticed the change in her voice, and many observed the change in her countenance. They saw the sudden transition from a deathlike paleness to the flush of health, as the natural color was seen, first in her neck, then in the lower part of the face, and then in the forehead. One of the business men of Healdsburg exclaimed, “A miracle is being wrought in sight of this whole congregation!” After the meeting she testified to inquiring friends that the Lord had healed her. With the healing came strength and courage to labor, and during the remainder of the meeting she spoke five times. LS 263.1"
"And he took him by the right hand, and lifted him up: and immediately his feet and ankle bones received strength. And he leaping up stood, and walked, and entered with them into the temple, walking, and leaping, and praising God."
Both passages describe a sudden physical healing that is witnessed by a crowd. The EGW passage describes a restoration of health and color, while Acts 3:7-8 describes the strengthening of feet and ankles. The core theme of miraculous healing is present in both.
"“At the close of the discourse [Sabbath afternoon], ... she arose and began to address the people. Her voice and appearance changed, and she spoke for some time with clearness and energy. She then invited those who wished to make a start in the service of God, and those who were far backslidden, to come forward, and a goodly number answered the call.... LS 263.3"
"And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance."
Both passages describe a change in speech and appearance, accompanied by a powerful effect on the audience. In Acts, it's speaking in tongues; in EGW, it's clear and energetic speech leading to a call to action. The common thread is empowerment by the Spirit leading to effective communication.
